Company Updates



A Letter from the OneMarketData Team:

2023 represented a mix of resilience, uncertainty, and innovation for markets around the globe. The market navigated periods of volatility stemming from geopolitical tensions, inflationary pressures, and ongoing supply chain disruptions; and despite these many challenges, many major indices reached record highs in 2023. We are proud that OneTick customers were able to rely on our platform, products and services to sail through uncertainty. 

The OneTick team made significant strides in our technical advancements and achieved landmark customer success in 2023. Notable technology milestones included the incorporation of real-time data into OneTick Cloud through our partnership with Options Technology, a major provider of cloud-enabled managed services to the global financial sector. We added a wide range of new clients including sell-side firms, asset managers, proprietary trading firms, vendors and marketplaces. We announced that the Financial Conduct Authority selected OneTick for its primary market surveillance and visualization system in a significant development for UK financial market regulation. We are thrilled to continue working in close collaboration with our customers to expand our range of products and services. 

As we kick off 2024, we are excited to announce OneTick’s expanded capabilities in real time and historical data enhancement to address the demanding needs of quantitative applications. This includes integrating reference and corporate actions data, applying analytics, curating symbol lists, and statistically measuring data quality. OneTick is increasingly chosen as the top collection and retention utility by legacy and new clients. As many content owners now focus on proactively enabling their content and data modeling within commercial cloud providers (AWS/GCP/Azure), the market is demanding greater transparency into data quality for self-collected and cloud data. OneTick is adapting to these market changes to serve as your top choice data collection and ​​expert data quality metrics platform.

We are incredibly grateful for your business in 2023, and hope you’ll read our company updates below to learn about our new customer highlights, product updates and company announcements.  We look forward to continuing to partner with you in 2024.

Client Updates

Today, OneTick works with more than 160 customers who rely on our solutions and services to deliver value across all asset classes. While we grew our existing business with long-standing customers in 2023, we also welcomed a substantial number of new clients to our OneTick platform.

In 2023, we helped a wide range of customers meet their needs, including US investment management companies, US banks, UK regulatory authorities, and EU banks to name a few. The company announced the competitive bid selection for the Financial Conduct Authority (FCA); partnered with a Swedish bank, a major Swiss bank, and a large Australian online broker on major projects; and significantly expanded our deployment for one of the world’s largest stock exchange groups. We also signed with one of Europe's largest generators of renewable energy.

Python-First Tick Data Analytics: OneTick-py

onetick-py offers a ground-breaking paradigm for working with tick data: a highly performant domain specific language is available via pandas syntax. onetick-py exposes the full power of OneTick via a pandas-like Python API expanding a familiar DataFrame paradigm to include common time series operations running at the speed of C++. Customers can access tick-by-tick data from 200+ exchanges using onetick-py for quant research, BestEx, TCA, backtesting, etc. Head to to see more.

Machine Learning

OneTick has three new machine learning (ML) offerings: a library for ML experiments, MLOps as a service, and hosted market impact models.

onetick-ml is a Python library for streamlining machine learning experiments with features derived from tick data. Customers can define ML experiments in just a few lines, iterate easily over different features/models/hyperparameters, share results with colleagues, and monitor and serve models in production. Prepare tick data features using the full power of OneTick at hand to prepare the features from tick data. See for details.

Customers with no MLOps infrastructure or market data experience can start experimenting with machine learning right away in OneTick's hosted environment, accessing decades of tick-by-tick market data from over 200 exchanges. OneTick will host the models and take care of model monitoring and re-training.

In 2023, OneTick's ML team leveraged its extensive collection of tick-by-tick market data to create market impact models that are available via API. A customer can specify the security, the quantity to execute, and the time horizon to get the predicted market impact. The models can be custom-trained for customer use cases.

OneMarketData continues to deliver the technology innovation, expertise and exceptional customer experience its clients require to navigate dynamic market risks, regulatory requirements, geopolitical events, and the new realities of cryptocurrency markets.

In 2023 we invested significantly to support the unprecedented demand for OneTick Trade Surveillance. We continue to work closely with our clients to deliver new features and functionality to meet their most complex data, analytics and regulatory requirements.
